Hydraulic Products, X64 Range - ISO 16028 Flat-Face Pressure Eliminator Nipples

Series 064 DN25 Pressure Eliminator

  • Flat-Face design
  • Connection under pressure
  • One-hand operated

CEJN Series 064 is a Flat-Face quick-connect nipple with a built-in pressure eliminator. The nipple is according to and exceeds the demands in the ISO 16028 Standard for low- and medium-pressure hydraulic applications. The Flat-Face design minimizes spillage during connection and disconnection. The pressure eliminator allows for connection with residual/trapped pressure on the nipple side. The nipple Series 064 connects with couplings in Series 065.

The pressure eliminator nipples are also available in five smaller sizes; DN 6.3 (Series 264), DN 10 (Series 364), DN 12.5 (Series 564), DN 16 (Series 664) and DN19 (764).
